We can define lambda expression in C# as, Here, 1. parameterList- list of input parameters 2. =>- a lambda operator 3. lambda body- can be an expression or statement Based on lambda body, the C# lambda expression is divided into two types.
The two types of lambda expressions are: 1. Expression Lambda 2. Statement Lambda 1. Expression Lambda:Expression lambda contains a single expression in the lambda body. For example, The above expression lambda contains a single expression num * 5 in the lambda body. It takes an int input, multiplies it by 5, and returns the output. 2. Statement La...
Output In the above example, the expression lambda is Here, the expression lambda returns the square of num. We have then assigned the expression lambda to the squarevariable. So, when we pass 5 as an input in square, we get 25as an output.
Output In the above example, we have used the statement lambda as, Here, the statement lambda takes two integer parameters - a and b. On the right side of the lambda operator =>we have enclosed two statements that: 1. calculate the sum of a and b 2. return the sum
In C#, we can assign lambda expressions to the delegate types like Func. For example, Output In the above example, we have assigned lambda expression num => num * 3; to the Func delegate multiply. Here, the lambda expression takes an int type input num, multiplies it with 3 and returns the result to multiply(). Hence, when we pass 5 in multiply(), ...
Learn what is a lambda expression in C#, how to define it, and how to use it with delegates and methods. See examples of expression and statement lambdas, and how to pass parameters and return values.
May 17, 2024 · Learn how to use lambda expressions to create anonymous functions in C#. See the syntax, types, examples, and applications of lambda expressions in LINQ, delegates, and expression trees.
Learn how to create and use lambda expressions in C#, which are shorthand for writing anonymous functions. See how to replace delegate and anonymous methods with lambda expressions and simplify your code.
Sep 4, 2023 · In this article and code examples, we will see how to implement lambdas in C#. Lambda expressions are anonymous functions that contain expressions or sequences of operators. All lambda expressions use the lambda operator =>, which can be read as “goes to” or “becomes”. The left side of the lambda operator specifies the input parameters ...
